Abstract (en)
[origin: EP0351827A2] There are disclosed a process for producing a zirconia-based sintered material, which process comprises heating an amorphous material consisting of zirconium oxide containing about 9.5 - about 10.5 mol % (in terms of oxide) of cerium oxide and about 0.4 - about 3.0 mol % (in terms of oxide) of calcium oxide, to a temperature not lower than the temperature of crystallization of the amorphous material but not higher than about 1,200 DEG C, crushing the resulting material to obtain a powder containing a tetragonal phase in an amount of about 90% by weight or more, and then subjecting the powder to molding and sintering, and a sintered material thus produced.
